I could try an easy test outside of sextante/qgis by renaming my saga install folder and trying to run a simple command.

IMHO the Good Way would be to split saga_gui and saga_cmd packages, and include only
the latter. We have been discussing about this in the saga ML, and my understanding
is that this is feasible, but may require some work upstream.
Bringing wxpy requirement in qgis package is likely to create some trouble so bettar
avoiding it if possible.
All the best.
